no the Infinity References were pretty much plug and play, 4 inch fit. The speakers had 4 holes instead of OEM 3 holes, but that can be easily modified to fit the speaker into the existing hole/mounting location.

I run them off the head unit just like the standard speakers, however the sound quality is better and fidelity / clarity is greater as well due to an in-built tweeter.

The total cost was $110 from a local audio shop, so quite a cheap mod.
